As a coin has two sides, the odds are always 50-50.
None, since that would imply that in 18 cases the coin did not show heads or tails!
Heads - ½ Tails - ½ There are two reasonable outcomes of flipping a coin. You could get heads or tails. Some might argue that the third outcome is that the coin will land on the edge.
The probability of NOT getting heads is (1/2)4=1/16 Therefore the probability of getting heads is 1-1/16=15/16
The event is that the coin lands with the Heads on top.
The probability of flipping a coin 3 times and getting 3 heads is 1/2
There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.

As a coin has two sides, the odds are always 50-50.
The sample space when flipping a coin is [heads, tails].
The probability of this is 50%. 2/4
